Hazelnut Dacquoise With Chocolate Ganache Filling Recipes

DACQUOISE

Steps:

• Position the oven racks in the upper, middle, and bottom part of the oven, then set the oven to preheat to 150 °C. Line three 21 cm round baking pans or trays with parchment paper or, if you are using trays, draw a 21 cm diameter circle on each. Set aside.
• In a small bowl combine hazelnuts, 100 grams of caster sugar, and cornflour. Whisk egg whites with a pinch of salt at medium speed for 2 minutes. Increase the speed to high, and with the mixer running, gradually add 200 grams of sugar until stiff glossy peaks. Fold the hazelnut mixture into the meringue.
• Spoon the meringue into a piping bag fitted with a 1.5 cm plain tube. Pipe a spiral of meringue starting from the center of each drawn circle and working outwards. Bake for an hour, rotating the upper and bottom baking tray after 30 minutes, so they cook evenly. Turn off, and leave the meringues to cool down in the oven with the door slightly open.
• To make chocolate ganache, place the chopped chocolate in a heatproof bowl. Heat the cream until hot, just simmering, but not boiling and pour over the chocolate. Let sit for a minute and then stir until smooth. Cool to room temperature, then refrigerate until it thickens. Fill the piping bag fitted with a medium star nozzle with ganache and set aside.
• To make the custard, bring the milk to a boil over low heat. Whisk the egg yolks, sugar, and coffee and chicory essence, then whisk in the cornflour, a tablespoon at a time. Pour the hot milk over the egg mixture, whisking continuously, then pour the mixture back into the pan. While constantly whisking, bring to a boil, then decrease the heat, and let it simmer for 2-3 minutes until thick and smooth. Remove from the stovetop and wait an hour for it to cool. Once the custard is chilled, fold in softly whipped cream.
• Whip the cream until soft peaks. Whisk half of the whipped cream into the cold coffee mixture, then gently fold in the rest. Cover and chill until needed.
• Melt sugar in a small frying pan (without stirring). Cook until golden caramel color, or until a thermometer registers 300°C. At that point add the whole hazelnuts and lemon juice, and stir with a wooden spoon until well blended. Pour the mixture onto a baking tray lined either with baking paper or silicone. Using two teaspoons form 12 pieces of hazelnut praline. Wait for it to cool completely before use.
• Position one meringue layer on a large serving plate, then in an even layer, coat it with one-third of the coffee cream. Place a second meringue layer on the cream to cover, then spread the top part with half of the coffee cream. Top with the third meringue layer, coat the sides of the cake with the coffee cream. Press roasted and chopped nuts into the sides of the cake. Pipe 12 swirls of the ganache onto the top outer edge of the cake, taking care they are evenly spaced, then place a piece of praline on each.

HAZELNUT-MOCHA DACQUOISE

Steps:

• Position racks in the upper and lower thirds of the oven and preheat to 325 degrees F. Spread the hazelnuts on a baking sheet and bake until toasted, 12 to 15 minutes; let cool completely. Combine 1 cup each hazelnuts and sugar and the potato starch in a blender or food processor and pulse until very finely ground. Transfer to a large bowl.
• Reduce the oven temperature to 275 degrees F. Line 2 large baking sheets with parchment paper. Using a bowl as a guide, draw three 7-inch circles on the parchment with a pencil (2 circles on 1 piece and 1 circle on the other); flip the parchment so the markings face down.
• Put the egg whites, 1/2 cup sugar and the salt in a large heatproof bowl. Set over a saucepan of simmering water (do not let the bowl touch the water) and whisk until the sugar is dissolved and the mixture is warm, 2 to 5 minutes. Remove the bowl from the saucepan and beat with a mixer on medium-high speed until stiff and shiny but not dry, about 2 minutes.
• Fold the milk and one-quarter of the egg white mixture into the nut mixture with a rubber spatula until smooth, then fold in the remaining egg whites until just combined. Divide the batter among the 3 circles on the parchment and spread evenly with an offset spatula to fill the circles. Bake 1 hour, 30 minutes, then switch the position of the pans and continue baking until firm, dry and golden, 1 to 2 more hours. (The layers are done when they easily peel off the parchment.) Let cool slightly on the baking sheets; peel off the parchment and transfer to a rack to cool completely.
• Meanwhile, make the ganache: Put 1 cup cream in a microwave-safe bowl; microwave until very hot, about 2 minutes. Whisk in the chocolate and espresso powder until smooth. Let cool to room temperature, then cover and refrigerate until cold, thick and spreadable, at least 30 minutes. Make the whipped cream: Combine the remaining 4 cups cream and 1/3 cup sugar in a large bowl and beat with a mixer on medium speed until it barely holds soft peaks, 1 to 2 minutes. Finish beating the cream by hand with a whisk until soft peaks form; do not overbeat.
• Put 2 meringue layers on a baking sheet; spread half of the ganache on each, to the edge. Refrigerate until set, 15 minutes. (If the ganache is too firm to spread, microwave in 20-second intervals to soften.) Place one of the ganache-topped meringues on a platter. Spread with 1 cup whipped cream. Stack the other ganache-topped meringue on top; spread with another layer of whipped cream. Top with the last meringue, then cover the top and side of the cake with the remaining whipped cream. Chop the remaining 1/3 cup hazelnuts and sprinkle on top of the cake along with the shaved chocolate. Refrigerate at least 6 hours or overnight before serving.

HAZELNUT DACQUOISE WITH CHOCOLATE GANACHE FILLING

Steps:

• Meringue
• Preheat oven to 325°F (180°C).
• Process hazelnuts with ¼ cup (50 mL) of sugar in food processor until coarsely chopped. Remove 2 tbsp (30 mL); reserve for garnish. Continue processing hazelnuts until finely chopped.
• Line bottoms of two baking sheets with parchment paper. On each, draw two 4 x 8-inch (10 x 20 cm) rectangles. Turn paper over; rectangles should be visible.
• Beat egg whites with electric mixer until frothy. Add cream of tartar and beat until soft peaks form. Add remaining sugar, about 1 tbsp (15 mL) at a time, beating until sugar is dissolved and stiff peaks form. Gently fold in hazelnuts. Spoon one quarter of the mixture over each rectangle; spread evenly to fill space.
• Bake in a preheated 325°F (180°C) oven until crisp on the outside and light golden in colour, about 25 minutes. Let cool on baking sheets.
• Filling
• When ready to assemble, heat chocolate and ⅓ cup (75 mL) whipping cream in microwave on High power until chocolate is partially melted, about 40 seconds. Stir until completely melted; set aside.
• Whip remaining cream on high until stiff peaks form. Gently fold in chocolate until blended.
• Carefully peel one meringue from parchment paper; place on serving plate. Spread one quarter of filling over meringue. Continue layering remaining meringues and filling, ending with layer of filling. Sprinkle reserved hazelnuts over top.
• Refrigerate for at least 2 hours or overnight before cutting into slices with serrated knife to serve.
